Bring your idea to life faster

Build What They Love
Using the product strategy builder, you can get clear on who your product is for and what problem it solves, ensuring that you build something people really want to use.
Prioritize The Best Features
By capturing how each feature helps the application and your business through business cases, you can stay focused on building the most critical features first.
Meet Your Requests
By documenting explicit requirements for a feature in a specification, you can ensure you build what your users and clients have asked for.
Plan Faster
Having your product strategy, ideas for new features, specifications, release planning, and progress reporting all in one application allows for faster project planning.
Develop Faster
Capturing precise specifications with itemized requirements enables your developers to progress faster, and reduce re-work, reducing your development costs.
Stay Focused
By using business cases to classify features, less critical or irrelevant features become apparent, and you can avoid wasting time on them.
By sharing ideas and drafts across an online platform, your team can develop specifications with requirements much faster.
Faster Reporting
Through the live-updating dashboards, you can easily communicate project progress across your business without needing to assemble progress reports manually.
Reduce Your Costs
Through the small teams plan and low cost per user, you can save money compared to most other products in this category.
Know Your Journey
By developing a product strategy upfront, you can be clear on who your product will serve and what problems it will solve before you start developing. A clear strategy reduces the risk you are creating something that is not needed.
Keep All Critical Information
Through the change tracking system, you can view all changes made to specifications and never lose information from earlier iterations.
Keep Requirements Clear
By documenting specifications for each feature before development, you can ensure there is a clear understanding between you and an external development agency before coding.
